Summer may be almost over, but that doesn't mean all the fun needs to come to a screeching halt on September 1.

If you didn’t get your fix of balmy weather over the last few months, then these totally budget-friendly flight deals across the country are for you.

According to travel search engine's data — based on median round-trip ticket prices when factoring in domestic departure points from coast to coast — travelers can still score tickets to warm weather spots like Orlando, Las Vegas, Miami, Los Angeles, and New Orleans for less than $300 between September 15 and November 11.

Check out a few of their most popular (and affordable) domestic travel destinations, along with one deal on a popular international trip, below.

Orlando: $218

The family-friendly destination is the perfect spot for a quick weekend getaway with the kids to celebrate the new school year, and with a median price tag of just $218 a piece, it’s budget-friendly as well. And while Walt Disney may have put Orlando on the map, there are plenty of other things to see and do when visiting the Florida city, including world-class shopping and dining in downtown Orlando.

Las Vegas: $228

On the other side of the travel spectrum, Las Vegas is a prime fall travel destination for adults looking to have a little kid-free fun. The temperatures will still be hovering in the 90s, but are far more bearable in the fall months. This means sitting by the pool with a cocktail all day is in the cards, while you wait for the sun to go down so you can catch a show and gamble away a few of your hard-earned dollars. And with flights at just $228, this also means visitors can splurge on a nicer hotel, dining experience, or simply throw a few more bills down at the blackjack table.

Miami: $256

Honestly, there may be no better fall getaway in America than Miami. Visitors can fly down to the Florida city for a mere $256 and lounge about on the shores, take a dip in the crystal blue waters, shop to their heart’s content along Ocean Drive or simply sip a few mojitos in Little Havana. No matter what you choose to do you really can’t go wrong. Check out our guide to Miami before booking your ticket here.

Los Angeles: $217

Something surprising happens in Los Angeles in September: The weather actually gets warmer. Seriously, the warmest month for the Southern California city is September, when temperatures hover around 76 degrees, making it a perfect spot to extend your summer vacation. And at $217 per flight, you could even come back more than once to experience everything the city has to offer, from the Downtown Arts District to the yoga-loving hippies in Venice Beach.

Denver: $186

While it may not be the warmest spot on our list, Denver does have one thing that makes missing out on higher temperatures worth it: major leaf peeping.

Seriously, it may sound dull to some, but seeing the changing fall colors in a stunning place like Denver will leave you breathless, we guarantee it.

Head to the Mile-high City to check out some of the spectacular dining and shopping destinations, then drive out to one of the picture-perfect hiking spots to see the fiery-colored, changing leaves. Read more in our guide to hiking around Denver here.

San Juan, Puerto Rico: $145

We can’t stress enough how easy it is to feel worlds away by simply hopping on a plane and heading down to Puerto Rico.

The U.S. territory is a mere three and a half hours from New York by plane. Moreover, it’s crazy cheap, as according to Kayak, one can fly to San Juan for just $145 in the third weekend in September. Once there, book a car and travel around the island to visit the only rainforest in the United States National Forest System and a few of Puerto Rico’s famed beaches, then end your day back in Old San Juan to dine at one of its amazing restaurants.

Bonus destination: Havana, Cuba

If you’re looking to explore a destination outside the U.S., then Havana, Cuba may be the right spot for you.

According to Kayak, the city, which can be reached for around $300, was named its number one trending destination this year and continues to make appearances on both its spring break and summer travel lists. But, with the future of travel to Cuba uncertain, it will be interesting to watch how new policies impact the destinations in the coming months, so perhaps now is the time to see Havana before it gets more complicated.
